#' Plot an adjacency or incidence Matrix
#'
#' @param Mat : a matrix representing the network
#' @param dimLabels : a vector of length 1 or 2 specifying the types of nodes in row and col (functional group) (Default is \code{NULL})
#' @param clustering : a list of length 2 specifying a clustering on row and col
#' @param plotOptions : a list providing options. See details below.
#' @details The list of parameters \code{plotOptions} for the matrix plot is
#' * "legend": Boolean. Set TRUE if you want to see the legend. Default value is FALSE
#' * "legend.title": Boolean. Set TRUE if you want to print the title of the legend. Default value is FALSE
#' * "legend.position": Position of the legend. Possible values are 'bottom', 'top','left,'right'. Default value is 'bottom'
#' * "rowNames": Set true if the rownames must be plotted. Default value is FALSE
#' * "colNames": Set true if the colNames must be plotted. Default value is FALSE
#' * "line.color": Chain of character. The color of the lines to separate groups if a clustering is provided. Default value is red
#' * "line.width": Numeric. Width of the lines to separate groups. Default value is NULL, automatically chosen
#' * "title": Chain of character. Title of the plot. Default value is NULL
